Which character(s) in Dead Poets Society illustrate(s) Holden's observations about life and people from The Catcher in the Rye? Why?
So, you're asking which characters in Dead Poets Society illustrate Holden's observations about people in The Catcher in the Rye?
In the movie, Holden matches up with the Todd character, I suppose. Neil would be James Castle, the one who commits suicide. Knox matches up with the sex-driven Stadlater, although Knox doesn't seem as arrogant.
Neil's father, obviously, would be considered a phony. He limits his son's freedom of choice in achieving his happiness in becoming an actor. Mr. Perry's obsession for his son to become a doctor is deterministic and materialistic.
Mr. Keating, then, would be like Mr. Antollini. In Catcher, Mr. Antolini is the teacher who finds Castle's body and shields it from the gawking boys. In this way, he was a catcher in the rye. Although he could not stop the suicide, he did provide dignity to the body. Mr. Keating is very similar; he becomes the fall guy in the suicide, losing his job. Todd honors him at the end by standing on the desk, showing his teacher that he is not afraid to stand up to authority.
